Borneo Hillstream Loach (Pseudogastromyzon sp.) for Sale in Canada
The Borneo Hillstream Loach (Pseudogastromyzon sp.), available under stock code 2403, is a fascinating freshwater species famous for its unusual flat body shape, powerful suction ability, and adaptation to fast-flowing streams. This rare loach is a favourite among aquarists who enjoy natural river-style aquariums and unique algae-grazing fish.
Unlike traditional bottom-dwelling loaches, the Borneo Hillstream Loach has evolved a flattened body that allows it to cling tightly to rocks and aquarium surfaces in strong currents. Its peaceful nature, interesting behaviour, and excellent algae-grazing ability make it a perfect addition to mature planted and river aquariums.
